- Exploring determinants of trust In emerging technologies : an integrative Pls-Sem and Multi-Group AnalysisPublication . Kireeva, Tatiana; Scott, Ian James; Almeida, Filipa deThis thesis aimed at investigating factors that determine technology trust beliefs and, more specifically, at the differences between such factors for emerging and existing technologies. It was the first research to test the “Faith-Confidence” grouping of technology trust predictors. The thesis is comprised of two studies. PLSSEM technique was used in Study 1 to examine the structural model, which included a set of individual differences, institutional-based trust, concern about privacy, calculus-based trust, and social norms. Study 2 tackled limitations of Study 1 and further assessed the relationships between the above-mentioned variables and technology trusting beliefs. In addition, by conducting a multi-group analysis, it compared the strength of the path estimates between technologies. Study 1 and Study 2 were controlled randomized post-test experiments (total N= 629). Major findings included the significant observed difference between how trust is developed for emerging versus non-emerging technologies, which unfolded a research gap in the current literature. The studies further tested hypotheses, related to the “Faith” or “Confidence” technology trust predictors. Results suggest that “Faith” has a higher predictive value for trust in emerging technologies, while “Confidence” does for existing technologies. Furthermore, the thesis’ unique contributions included the development of two new constructs – perceived power asymmetry and technological savviness – for the technology acceptance domain. Future research should focus on replication of these studies for various technologies and cultures to ensure the results’ external validity, and try to expand the proposed model on the actual technology usage.
- How many is too many? Exploring the impact of number of eco labels on sustainability perception and willingness to buy textile goodsPublication . Gertzen, Divine; Scott, Ian James; Almeida, Filipa deStudies on environmental management are increasingly focusing on the role that ecolabels play in the textile sector in helping customers make educated decisions about their purchases. This study aimed to contribute to the existing literature by investigating the research question: How many labels would be the optimum amount to have in order to increase the sustainability perception and WTB? Trust, information overload, consumers’ scepticism and environmental concern were investigated to understand their impact on the WTB and sustainability perception of consumers. The findings from this study (N =533) highlighted a significant role of information overload on the sustainability perception and WTB. The optimal number of labels could not be established, however multiplicity had a direct effect on the WTB. This study revealed that the effect of eco labels had a positive influence on the sustainability perception. However, they also had a negative influence on information overload, which impacted WTB. Further academic contributions as well as practical implications for businesses and policy makers emerge, such as the creation and unification of common guidelines of environmental claims at EU or even transnational level.
